Title: Image memory display controller
Inventor: MASUDA NOBUKO
IPC: G09G5/00
Filed: 1988-02-09
Abstract: PURPOSE:To obtain a high speed image memory display controller, which does not make any turbulence on a display screen, by releasing CPU's image memory access in the fall of a clock whose phase is delayed in the same cycle as the clock of a display memory address counter. CONSTITUTION:A clock supply part 11 outputs a clock signal CLKB 112 whose phase is delayed by 3/4 of a clock signal CLKA 111 and a clock signal CLKB 112 whose phase is delayed by 7/8 of a clock signal CLKA 113 to a sampling part 12. CPU's image memory access command and NCPU's command 000 at low level are sampled in the rise of the CLKB 112, and access of the CPU 3 is released in the fall of the CLKC 113. The use of a low speed memory is possible by accessing the image memory by external devices such as the CPU, etc., once out of twice of display memory address cycle. Also, waiting time of the external devices as CPU etc., has hardly changed as before. Therefore, the high speed image memory display controller free of turbulence on the display screen is obtained.

Abstract: PURPOSE:To generate correction current to securely cancel a magnetic field and to correctly measure magnetic bubbles by detecting a magnetic field from a ring magnet which cannot be canceled by a Hall element as noise by means of a canceled magnetic field detecting element. CONSTITUTION:A ring magnet (permanent magnet) 5 is fixed to a rotation axis of an object to be measured.

Immediately after this, switches 26, 27 are turned ON to subtract outputs of the S/H circuits 23, 24 from a two-phase signal of a two-phase oscillator 25 to have them corrected and the signals are read by coils 3, 4. As for a magnetic field which cannot be yet canceled, two canceled magnetic field detecting elements 32, 33 and a transfer element are placed in parallel, and Barkhausen noise is extracted from their differential outputs to obtain a generation interval of the noise, which is to be supplied to subtractors 28, 29 as a correction value of the canceled magnetic field.

Abstract: PURPOSE:To obtain a semiconductor device which has a small parasitic capacity and from which leakage currents are reduced by forming an emitter and collector areas by diffusing an impurity of first conductivity type through an electrode section. CONSTITUTION:An insulating film 160 is formed on an island area 103 of second conductivity type formed on the surface of a semiconductor substrate 101. Then an emitter and collector areas 155a and 155b are formed by forming a buried emitter and collector electrodes 108a and 108b and diffusing an impurity of second conductivity type. Therefore, the junction capacitance of this semiconductor device can be made smaller as compared with the conventional semiconductor device. In addition, generation of leakage currents can be prevented, because the insulating film 160 is brought into contact with the emitter and collector areas 155a and 155b and a base area formed between the areas 155a and 155b.
